Question #170543

How many formula units of ammonium carbonate are present in 82 grams of carbon?

Expert's answer

Molar mass of ammonium carbonate is 96.11

and formula mass of ammonium carbonate= 96.11

and formula mass of Carbon=12 g

formmu;a unit of 82g of C= "\\frac{82}{12}=6.833"

Formula of ammonium carbonate=(NH_{4})_{2}CO_{3}

one formula unit of ammonium carbonate has 1 carbon unit

so 6.833 unit of C= 6.833 formula unit of ammonium carbonate
